Reactive Collisions of Electrons with Molecular Cations: Application to H-2(+), BeH+, BF+

The processes as: dissociative recombination, dissociative excitation and inelastic or super-elastic collision of molecular cations with electrons are major elementary process in the kinetics and in the energy balance of astrophysically-relevant ionized media (interstellar molecular clouds, planetary atmospheres, early Universe), in edge fusion and in many other cold media. In this work the main interactions and mechanisms governing these processes, successfully modelled by the Multichannel Quantum Defect Theory (MQDT) are presented. Using a stepwise method based on this theory, cross sections and rate coefficients have been obtained for reactions induced on H-2(+), BeH+ and BF+.
